A COUPLE of Chris Greenacre strikes and another from Mathew Piper sank Swansea without trace as the Stags tightened things up at the Third Division summit.

Billy Dearden's Stags roared to a 12th league maximum of the season and they were on their way after just 14 minutes as #500,000 rated Greenacre - once on loan at Cardiff - netted with ease.

And they were flying home as they added more goals either side of the break with Greenacre and Piper lifting the home crowd.

Swansea made just one change to the side who nose-dived to Hartlepool at The Vetch eight days previously - veteran skipper Nick Cusack returning to the centre of midfield, Steve Brodie dropping to the bench.

Premiership Leicester, Middlesborough, Nationwide League Barnsley and QPR had also dispatched scouts to Field Mill to watch Swans hot-shot Mamady Sidibie.

But third-placed Mansfield were ahead against the run of play on 14 minutes.

Tankard's ball fatally pierced the Swans, Chris Greenacre notching his 16th goal of the season from 10 yards.

Colin Addison's men could have been level just four minutes later though.

Kris O'Leary's left side cross sparked bedlam in the Stacks area, John Williams' mis-kicking before Coates lashed the rebound inches wide.

Mansfield pressure was steepling and Swansea finally collapsed again on the stroke of the break - Greenacre's drive whistling past Freestone, thanks to a big deflection off Jason Smith.

Swansea were wielding the changes at the restart - former Merthyr defender Neil Sharp and Brodie entering the fray, Smith and Damien Lacey drifting off .

Cusack saw a couple of rockets stopped by Stags stopper Kevin Pilkington and Sharp's header hacked to safety off the line by Les Robinson.
